Wound Care Certification Exam Wound Care Certification Wound Assessment and Staging 2 — Questions and Answers
Question 1: A patient has a pressure injury where the wound bed is not visible due to slough covering the entire base. How should this wound be staged?
- Stage 3
- Stage 4
- Unstageable (Correct answer)
- Deep Tissue Pressure Injury
Correct answer: Unstageable
When slough or eschar obscures the wound bed, the wound is classified as Unstageable because depth cannot be determined.
Question 2: Which characteristic distinguishes a Stage 3 pressure injury from a Stage 4 pressure injury?
- Presence of tunneling
- Exposure of bone, tendon, or muscle (Correct answer)
- Depth extending through dermis
- Presence of slough in the wound bed
Correct answer: Exposure of bone, tendon, or muscle
Stage 4 pressure injuries involve full-thickness tissue loss with exposed bone, tendon, or muscle, distinguishing them from Stage 3.
Question 3: When measuring a wound, what is the correct anatomical orientation for wound length?
- Head to toe (superior to inferior) (Correct answer)
- Side to side (medial to lateral)
- Diagonal from corner to corner
- Widest dimension regardless of direction
Correct answer: Head to toe (superior to inferior)
Wound length is measured head to toe (superior to inferior) using the clock face analogy with 12 o'clock toward the head.
Question 4: A clinician documents wound undermining at '9 to 12 o'clock, extends 2 cm.' Using the clock face method, where is this undermining located?
- On the patient's right lateral to superior border (Correct answer)
- On the patient's left lateral to superior border
- On the patient's right medial to inferior border
- On the patient's inferior to left lateral border
Correct answer: On the patient's right lateral to superior border
With 12 o'clock toward the head, 9 o'clock is the patient's right side and 12 o'clock is superior, so undermining spans right lateral to superior.
Question 5: Which wound exudate characteristic is most concerning and warrants immediate clinical evaluation?
- Serous exudate in a healing wound
- Serosanguineous drainage after debridement
- Purulent exudate with foul odor (Correct answer)
- Increased drainage after compression therapy
Correct answer: Purulent exudate with foul odor
Purulent exudate with foul odor indicates infection and requires immediate evaluation and intervention.
Question 6: What is the primary purpose of performing periwound skin assessment during wound evaluation?
- To determine wound staging
- To identify signs of wound edge complications and skin breakdown (Correct answer)
- To calculate total wound surface area
- To select appropriate wound dressing
Correct answer: To identify signs of wound edge complications and skin breakdown
Periwound assessment identifies complications such as maceration, induration, erythema, or satellite lesions that affect treatment planning.
Question 7: A diabetic patient presents with a wound on the plantar surface of the foot over the first metatarsal head. What wound classification system is most appropriate?
- NPUAP pressure injury staging
- Wagner Ulcer Classification (Correct answer)
- CEAP classification
- Bates-Jensen Wound Assessment Tool
Correct answer: Wagner Ulcer Classification
The Wagner Ulcer Classification System is specifically designed for diabetic foot ulcers and grades severity from 0 to 5.
